We have made an experiment by partially replacing fine aggregate and coarse aggregate with plastic powder and ceramic waste respectively. The strength properties of M20 grade concrete are studied with different plastic powder and ceramic waste percentage proportions. The proportions are 15% of plastic powder, 15% of ceramic waste and 20% of plastic powder, 20% of ceramic waste are replaced with fine and coarse aggregate by volume. We studied strength properties of these mixes. There is increase in compressive strength when the ratio of plastic and ceramic to fine and coarse aggregate respectively was minimum. The workability of the concrete mix has been increased. Based on the test results we can suggest that the plastic and ceramic can be used as alternative material within the small replacement proportions.
